本文介绍如何使用Spring WS搭建SOAP Web服务，包括配置文件spring-ws-servlet.xml的详细解析及客户端实现。重点讲解了payloadMapping配置及客户端SOAP消息构造。

6, 修改配置文件spring-ws-servlet.xml.

Java代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="payloadMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
<property name="endpointMap">
<map>
<entry key=”{http://www.fuxueliang.com/ws/hello}HelloRequest” />
<ref bean="helloEndpoint" />
</entry>
</map>
</property>
</bean>
<bean id="hello" class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">
<property name="wsdl" value="/WEB-INF/hello.wsdl"/>
</bean>
<bean id="helloEndpoint" class="org.rondy.ws.HelloEndPoint">
<property name="helloService" ref="helloService" />
</bean>
<bean id="helloService" class="org.rondy.service.HelloServiceImpl" />
</beans>

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">   <bean id="payloadMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">   <property name="endpointMap">    <map>     <entry key=”{http://www.fuxueliang.com/ws/hello}HelloRequest” />        <ref bean="helloEndpoint" />     </entry>    </map>   </property>  </bean>  <bean id="hello" class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">   <property name="wsdl" value="/WEB-INF/hello.wsdl"/>  </bean>  <bean id="helloEndpoint" class="org.rondy.ws.HelloEndPoint">   <property name="helloService" ref="helloService" />  </bean>  <bean id="helloService" class="org.rondy.service.HelloServiceImpl" /> </beans>

注: 其中最主要的bean就是payloadMapping, 它定义了接收到的message与endpoint之间的mapping关系:将SOAP Body中包含的xml的根节点的QName为{http://www.fuxueliang.com/ws/hello}HelloRequest交给helloEndpoint处理.
SimpleWsdl11Definition这个bean则是定义了这个服务的wsdl, 访问地址是:http://localhost:8080/springws/hello.wsdl.

7, 客户端(saaj实现)的代码如下:

Java代码

/**
*
* @author Rondy.F

*/
public class HelloWebServiceClient {
public static final String NAMESPACE_URI = "http://www.fuxueliang.com/ws/hello";
public static final String PREFIX = "tns";
private SOAPConnectionFactory connectionFactory;
private MessageFactory messageFactory;
private URL url;
public HelloWebServiceClient(String url) throws SOAPException, MalformedURLException {
connectionFactory = SOAPConnectionFactory.newInstance();
messageFactory = MessageFactory.newInstance();
this.url = new URL(url);
}
private SOAPMessage createHelloRequest() throws SOAPException {
SOAPMessage message = messageFactory.createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
Name helloRequestName = envelope.createName("HelloRequest", PREFIX, NAMESPACE_URI);
SOAPBodyElement helloRequestElement = message.getSOAPBody().addBodyElement(helloRequestName);
helloRequestElement.setValue("Rondy.F");
return message;
}
public void callWebService() throws SOAPException, IOException {
SOAPMessage request = createHelloRequest();
SOAPConnection connection = connectionFactory.createConnection();
SOAPMessage response = connection.call(request, url);
if (!response.getSOAPBody().hasFault()) {
writeHelloResponse(response);
} else {
SOAPFault fault = response.getSOAPBody().getFault();
System.err.println("Received SOAP Fault");
System.err.println("SOAP Fault Code :" + fault.getFaultCode());
System.err.println("SOAP Fault String :" + fault.getFaultString());
}
}
@SuppressWarnings("unchecked")
private void writeHelloResponse(SOAPMessage message) throws SOAPException {
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
Name helloResponseName = envelope.createName("HelloResponse", PREFIX, NAMESPACE_URI);
Iterator childElements = message.getSOAPBody().getChildElements(helloResponseName);
SOAPBodyElement helloResponseElement = (SOAPBodyElement) childElements.next();
String value = helloResponseElement.getTextContent();
System.out.println("Hello Response [" + value + "]");
}
public static void main(String[] args) throws Exception {
String url = "http://localhost:8080/springws";
HelloWebServiceClient helloClient = new HelloWebServiceClient(url);
helloClient.callWebService();
}
}

/**  *   * @author Rondy.F  *   */ public class HelloWebServiceClient {   public static final String NAMESPACE_URI = "http://www.fuxueliang.com/ws/hello";   public static final String PREFIX = "tns";   private SOAPConnectionFactory connectionFactory;   private MessageFactory messageFactory;   private URL url;   public HelloWebServiceClient(String url) throws SOAPException, MalformedURLException {   connectionFactory = SOAPConnectionFactory.newInstance();   messageFactory = MessageFactory.newInstance();   this.url = new URL(url);  }   private SOAPMessage createHelloRequest() throws SOAPException {   SOAPMessage message = messageFactory.createMessage();   SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();   Name helloRequestName = envelope.createName("HelloRequest", PREFIX, NAMESPACE_URI);   SOAPBodyElement helloRequestElement = message.getSOAPBody().addBodyElement(helloRequestName);   helloRequestElement.setValue("Rondy.F");   return message;  }   public void callWebService() throws SOAPException, IOException {   SOAPMessage request = createHelloRequest();   SOAPConnection connection = connectionFactory.createConnection();   SOAPMessage response = connection.call(request, url);   if (!response.getSOAPBody().hasFault()) {    writeHelloResponse(response);   } else {    SOAPFault fault = response.getSOAPBody().getFault();    System.err.println("Received SOAP Fault");    System.err.println("SOAP Fault Code :" + fault.getFaultCode());    System.err.println("SOAP Fault String :" + fault.getFaultString());   }  }   @SuppressWarnings("unchecked")  private void writeHelloResponse(SOAPMessage message) throws SOAPException {   SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();   Name helloResponseName = envelope.createName("HelloResponse", PREFIX, NAMESPACE_URI);   Iterator childElements = message.getSOAPBody().getChildElements(helloResponseName);   SOAPBodyElement helloResponseElement = (SOAPBodyElement) childElements.next();   String value = helloResponseElement.getTextContent();   System.out.println("Hello Response [" + value + "]");  }   public static void main(String[] args) throws Exception {   String url = "http://localhost:8080/springws";   HelloWebServiceClient helloClient = new HelloWebServiceClient(url);   helloClient.callWebService();  } }

几点看法:

1, 从上面代码可以看出, 比较麻烦的部分就是客户端和服务端对xml处理
